>Description:
VIA OUI is defined with the official 0x004063 value in miidevs, which in turn was copied from OpenBSD (relatively recently, rev=1.135). However, NetBSD recognizes VIA OUI as 0x0002c6, which coincidently matches with DATATRACK (unused?) value. Besides my own board, I verified that value is consistent with various vr0 dmesg reports in nycbug dmesg service and NetBSD mailing lists. Because of this VT6103 PHY description is not matched by ukphy driver.

Patch provided below. Tested with miiverbose enabled:

ukphy0 at vr0 phy 1: VT6103 10/100 PHY (OUI 0x0002c6, model 0x0032), rev. 10
